TALLAHASSEE -- A bill to extend subsidized health insurance to the state’s youngest legal immigrants has stalled in the Florida Legislature, due largely to the initial $27.5 million price tag.

But Rep. José Félix Díaz, a Miami Republican says the actual price is a lot lower: between $7 million and $15 million. He’s fighting to have the measure included in the state budget.

“If we don’t act, these kids will not get primary care,” said Díaz, whose bill would eliminate a five-year waiting period for coverage under Florida’s KidCare program. “They will enter our system with chronic issues.”

Díaz will have to move quickly. Both the House and Senate have finished preliminary budget proposals without including money to extend Florida KidCare to immigrant children. The legislative session ends May 2.

KidCare provides subsidized healthcare coverage to children from low- and moderate-income families. The program is backed by both state and federal funds.

In Florida, children born outside of the United States are not eligible for the program until they have been in the country for five years.

The waiting period was once required under federal law. But states now have the option to provide immediate coverage to immigrant children who are living in the state legally.

Diaz and Sen. René García, R-Hialeah, are pushing for the change.

The proposals (SB 282/HB 7) would not extend coverage to undocumented immigrant children, García noted in a recent committee hearing.

“This does nothing for those [children] who are here illegally,” García said. “This is for legally residing children. All we are doing is eliminating the five-year waiting period for them to qualify to get access to quality healthcare.”

His bill won the support of the Senate Health Policy Committee last month.

But both the García proposal and the one sponsored by Díaz have hit roadblocks because of the estimated cost as calculated by state policy analysts: $27.5 million to cover 22,903 children.

The estimate was later revised down by the House to $20 million.

Still, Senate President Don Gaetz said he was doubtful the bill would reach the Senate floor.

“Whether there are questions about the bill or not, the fact is, it hasn’t moved through the committees that it was referred to,” said Gaetz, a Niceville Republican. “Senators haven’t had a chance to ask their questions. The public hasn’t had a chance to have public hearings and to testify in all the committees of reference.”

Díaz sees another route: the state budget.

He says the measure would only apply to about 16,900 children — a figure he bases on the number of immigrant children who have been turned away for coverage in the past year. That would drop the cost to about $15 million, he said.

What’s more, if all children did not enroll immediately, the cost could drop as low as $7 million, Díaz said.

“It becomes affordable,” he said.

Díaz said he was especially encouraged after Friday’s announcement that the federal government would extend Florida’s “Low Income Pool” program, which pays for health services to poor and uninsured Floridians.

The state did not receive the bump in funding it had requested. But the $2.2 billion Florida will receive is enough to maintain the status quo.

“If we didn’t get the LIP dollars, it would have destroyed our healthcare budget,” Díaz said. “Now, I think we have the flexibility to fund programs like this one.”

Diaz said House Health Care Appropriations Subcommittee Chairman Matt Hudson was open to the possibility of incorporating the proposal in the budget, but Hudson, R-Naples, did not return calls Tuesday.

His counterpart in the Senate, Sen. Denise Grimsley, R-Sebring, did not return calls either.

Sen. Anitere Flores, a Miami Republican and the vice chair of the Senate Health and Human Services Appropriations Subcommittee, said she would be advocating for the plan.

“These are kids that have the right to have the insurance; the federal government has said it,” Flores said. “There is just a bureaucratic hurdle in the state of Florida that we should get rid of.”
